摘要： A system and method for defeating SYN attacks are provided. When the number of packets received by a server is above the capacity of the server, the server assumes that a SYN attack is in progress. The server randomly drops SYN packets without processing them. The percentage of SYN packets dropped is increased while the load on the server exceeds capacity, and decreased while the load on the server does not exceed capacity. Under attack conditions, a percentage of TCP connections are still maintained.

摘要： A computing device operating according to a frequency division multiplexed protocol in which communication occurs over a signal formed from a plurality of sub-channels selected from anywhere in a frequency spectrum. A computing device may select sub-channels cognitively by using information about sub-channels previously deemed suitable or unsuitable by that computing device or other computing devices. A described technique for determining sub-channel suitability includes analyzing radio frequency energy in the sub-channel to detect signals generated by another computing device or high noise levels. Information may also be used to cognitively select sub-channels to be analyzed, such as by first selecting for analysis previously-used sub-channels.

摘要： Guest user are enabled to access network resources through an enterprise network using a guest user account. A guest user account may be created for a guest for a limited time. Guest account credentials of the guest account may be provided to the guest to use the guest account using any of a variety of techniques described herein, for example, by scanning a guest access card, credit card or mobile telephone of guest user, and providing the guest account credentials to the user based on the information obtained. A guest access management server may be configured to generate and maintain guest accounts, authenticate guest users, and track and log guest activity. A VLAN technology may be used to separate guest traffic from host enterprise traffic on the host enterprise network. After a guest user is authenticated, communications to and from the guest user may be routed to a guest VLAN.

摘要： Mechanisms that allow IPv4 and IPv6 clients to communicate with reduced server workload. The IPv4 client initiates communication by routing an IPv4 message to a server. The server sends a similar IPv6 message to the IPv6 client. A relay intercepts the IPv6 response, generates an IPv4 response, and forwards that IPv4 response to the IPv4 client if the NAT is a cone NAT. Otherwise, the relay sends the IPv4 response to the server. The server includes the IPv4 address of the relay in the response and sends the response to the IPv4 client. The IPv4 client then communicates with the IPv6 client using the relay. The IPv6 client may also initiate communication with the IPv4 client by sending an IPv6 message to the relay where it is queued.
摘要翻译：允许IPv4和IPv6客户端与减少的服务器工作负载进行通信的机制。 IPv4客户端通过将IPv4消息路由到服务器来发起通信。服务器向IPv6客户端发送类似的IPv6消息。中继拦截IPv6响应，生成IPv4响应，并且如果NAT是锥形NAT，则将IPv4响应转发到IPv4客户端。否则，中继将向服务器发送IPv4响应。服务器在响应中包括中继的IPv4地址，并将响应发送给IPv4客户端。然后，IPv4客户端使用中继与IPv6客户端进行通信。 IPv6客户端还可以通过向中继站发送IPv6消息来发起与IPv4客户端的通信。

摘要： Systems and methods are provided that disclose a network service for modularly constructing a software defined radio (“SDR”). A server system provides an SDR kernel (i.e., a potentially platform-neutral definition of digital signal processing functionality and control operations necessary to implement the core portion of a software defined radio implementing a particular radio standard) to a client system. The client system may select a desired SDR kernel through a variety of means disclosed herein. While some SDR kernels may be provided for free and unrestricted use, others may be purchased or subscribed to and additionally restricted by digital rights management (“DRM”) policies. Based upon the agreed upon payment terms and any other restrictions, a customized set of DRM policies may be applied by the server system to the SDR kernel before sending it to a client system. Additionally, the server system may provide a description of governmental regulations applicable to a given locality.

摘要： A process for secure, safe, and easy provisioning of a wireless device with credentials to connect to a wireless network. A connecting wireless device and an established wireless device both utilize low power transmission at close proximity to exchange wireless connection setting information and/or a password. The connecting wireless device is moved into proximity with the established wireless device and a low power setting is discovered at which the wireless devices may communicate with a sufficiently low error rate. The connecting wireless device is then passed the secret information by the established network device.

摘要： A wireless device that desires to be connected to a wireless network broadcasts itself and its capabilities to a network using an information element. The information element is provided with frames, such as management frames, in a channel that is not protected or encrypted. The information element is forwarded to one or more potential registrar devices. One of the registrar devices then provides configuration information to the enrollee, for example as a registrar information element. The configuration information may be passed out of band or in band, and may be passed using cryptography, which may involve public key cryptography, encryption with a PIN, or some other type of secure exchange.

摘要： A method for ensuring valid and secure peer-to-peer communications in a group structure. Specifically, the system of the present invention presents a method of ensuring secure peer-to-peer group formation, group member addition, group member eviction, group information distribution, etc. Such functionality may be distributed to the individual peers in the group to further enhance the overall security of the group while enhancing flexibility. The P2P group security allows every peer who is a valid member of the group to invite new members. The recipients of these invitations are then able to contact any member of the group to join the group, not only the inviter. Further, groups may function when the group creator is not online. Likewise, the method allows the creation of secure groups with users from different security domains, relying on their security credentials in those domains for initial authentication.
